EN INE VALVE MECHANISM.

Specification of Letters Patent.

Batented June 3, 1913.

Original application filed March 23, 1912, Serial No. 685,866 Divided and. this application filed August 10,

1912. Serial No. 714,327.

To all whom it may concern:

Be it known that I, OSCAR TREIER, citizen of the Republic of Switzerland, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Engine Valve Mechanisms, of which the following is a specification.

and has for its object to provide a new and improved mechanism more especially designed for use in internal combustion en gines and arranged to insure proper opening and closing of the admission and exhaust valves.

This'application is a division from the application Serial No.,685,866,- filed March 23, 1912. l

A practical embodiment of my invention is represented in the accompanying drawing forming a part of this specification and in which similar reference letters indicate corresponding parts, Figure 1 being a section on line 11 of Fig. 2 and.Fig. 2 asectional top plan view of the engine.

'VVith reference to the drawing, each of the engine cylinders A has a single passage A which serves both for the admission and exhaust of the fuel. The tubular valve 1 is slidably mounted in the tubular chamber A which extends transversely to the said passage and to the said cylinders. This value has a closed inner end 2 and an open outer end 2 and divides the chamber A into two compartments of which the left pipe A communicating with the exhaust opening of the chamber A, while the right hand compartment is formed within the interior of the tubularvalve 1 and communicates with the supply pipe A? which leads into the admission opening of the chamberA. The tubular valve bears onv the inner surface of the chamber A by means of suitable packing rings 3 and is provided with circumferential openings 4. Within the valve body a spiral nozzle 5 is provided which projects toward andterminates near the innerclosed end 2 of the valve. This nozzle has its main object to cause a thorough mixture of the liquid gasolene wlth the air and another object to decrease the ten-' sion of the fuel prior to its entermg the cyl+ inder; A further result of the nozzle 19 Various means may be employed for opcrating the hollow valves, as for instance those shown in the drawing and particularly a as described in the application -above re- The present invention relates to valves ferred to.

It will be seen that when the valve occupies the position shown in Fig. 1 the passage mitted to exhaust through the said passage A of the cylinder will be opened a'nd the burnt fuel from the cylinder will be perand the circumferential openings A of the chamber A into the exhaust pipe A. On the other hand, when the valve body 1 moves to the left it will close the openings A", of i the chamber A and establish communication 1 between its own openings 4 and the passage Y A of the cylinder'A", so that fresh fuel entering the interior of the valve 1 and flowing through the spiral nozzle 5 will be admitted into the cylinder A. a

What I claim and desire to secure by Let ters Patent is:

1. In a valve mechanism for engines the the other and circumferential openings in alinement with the said passage, a tubular valve body slidably mounted in said c'hanlber and'having circumferential openings,

, the inner end of said valve body being ti ghtly, closed. and the outer end thereof being open, a nozzle in the interior of said tubular I valvedirected toward the said closed end of the latter, said valve being adapted to alter nately establish communication between the said cylinder and the said chamber to per: mit the fuel to exhaust, and between its interior and the said cylinder to admit fresh 'fueli .2...
